A reactive oligomer has a backbone derived from at least one of polyamideimide, polyimide, polyetherimide, polyaryletherketone, polyethersulfone, polyphenylene sulfide, polyamide, polyester, polyarylate, polyesteramide, polycarbonate, polybenzoxazole or polybenzimidazole and functionalized with at least one unreacted functional group capable of thermal chain extension and crosslinking after formation of the reactive oligomer, wherein the reactive oligomer has an M.sub.n of about 250 to about 10,000 g/mol, calculated using the Carothers equation. Compositions comprising the reactive oligomer have at least one other component that includes a second reactive oligomer, an oligomer lacking unreacted functional groups capable of thermal chain extension and crosslinking, a thermoplastic polymer, a thermoplastic polymer having the same backbone repeat units as the reactive oligomer, a filler, or an additive. A method of manufacture of an article comprises heating a composition comprising the reactive oligomer at a sufficient temperature and time to shape and crosslink the reactive oligomer, including additive manufacturing.

Described herein are methods for making poly(aryl ether sulfone) (“PAES”) polymers and polymer compositions including the PAES polymers. The method includes reacting a first monomer and a second monomer in a reaction mixture including a base. In some embodiments, the first monomer, second monomer and base can be selected such that halogen salts are not formed during the reacting. In some embodiments, the method can also be a solvent free process. The PAES polymer and polymer compositions can be desirable in many application settings including, but not limited to, electronic components.
